With the changes in our network we have a much greater need for data rich substations to support smart grid technologies and Asset management

We need a technology that can be deployed rapidly in strategic locations to support our DSO strategy

The technology required needs to achieve greater TOTEX cost efficiency than current technologies

Advantages

Compliance with standards specified can be verified and compared with vendor reports submitted for Assessment Consistent Assessment method across different vendor assets on the networkCyber security patches can be verified through regression testing very quickly in a lab environment closing vulnerabilities quickly and efficientlyIEC 61850 data attributes from logical nodes can be confirmed during Assessment phaseNetwork model can be easily modified for project specific queries or investigations New functions or upgrades can be assessed before being deployed on the live network

ConclusionsA new strategy on how we Assess a centralised protection and control system was required. This included an opportunity to align our specifications to the latest standards and communicate clearly to vendors

We identified opportunities to drastically reduce our substation footprint and reduce Engineering, Commissioning and maintenance time providing TOTEX cost efficiency benefits

Greater opportunities to complete full system testing prior to circuit transfers which reduces network risk and outage durations

Look to obtain additional funding in RIIO-ED2 (2023-2031) period to accelerate deployment of these systems
